Hopefully you purchased an SSR that can switch DC loads. An SSR for AC loads won't work with a DC power supply. Also note that you'll have to pay attention to the polarity of the control lines for the SSR. That didn't matter with the relay coil on the MakerFarm relay board but it does on the optical input stage of the SSR.
